Circuit is shown, which consists of voice electronic switch, light control switch, one-shot, controllable multivibrator circuit vocal music, counting / pulse distribution circuit ring, six-way driver circuit and the AC buck Lantern rectifier circuit. It can be a two-way flow in the lights, it is also accompanied by melodious music more than the first, Streamer, melodious music. (View)

The circuit shown in the figure, which consists of voice-activated switch, light control switch, one-shot timer circuit, control circuit and lights music sound circuit. The light control circuit 16 functions program can automatically transform, colorful, and its control method is sound, light double control, not light during the day, at night before proceeding voice. In the flickering lights, it is also accompanied by sweet waltz music. (View)

As shown, it is based on a voltage-controlled lantern audio control IC 5GM168 as the core, with the sound of birds and the sound amplifier circuit, consisting of a voltage-controlled lights and birdsong audio sound circuitry. (View)

As shown for the introduction of four lights 5GM168 composed of a control circuit (chip G-foot vacant), after four output current limiting resistor added to each VS1 ~ VS4 gate control their lights off and the corresponding road lanterns. BM is a pickup sensor. (View)

Circuit is shown, comprising a transducer microphone, voice circuit, thyristor control circuit, and the circuit share the music sound buck rectifier circuit. BH-SK-IV is the core component of the circuit.
